R. Mananathan, a technocrat in machinery & vibration analysis forms the company, Manatec to design and produce industrial shaft alignment computers. These computers work on micro-processor based design to measure and display misalignment between the shafts of any industrial prime mover.

Manatec designs another product electronic spirit level. Both shaft aligner & electronic spirit level were import-substitute products and received good response from the Indian market.

In 1991, automotive garage equipment used to be imported into India from Italy. Identifying the need for an import-substitute, Manatec with 100% indigenization, designed a wheel aligner for the first time in Asia

Manatec was awarded with Best productivity performance award for the year 1990-1991 from the National productivity council of India.

Manatec's wheel aligners were approved by major Indian vehicle manufacturers like Hindustan motors & TATA motors.
